Housing across Mid Glamorgan
The Rhondda, Cynon and Merthyr valleys are lined with stone terraces built for mining families, stepped along steep hillsides. Pontypridd, Caerphilly and Merthyr Tydfil have Victorian centres, and Bridgend has grown with large modern estates alongside interwar and post-war housing.
Valley terraces commonly need repointing, roof repairs, rendering and window replacement, and loft conversions can add useful space. Newer estate homes often take garage conversions, porches and landscaping.
The valleys get heavy rainfall and steep, sloping sites are common, so drainage, retaining walls and render specification matter.
Do you need permission in Mid Glamorgan?
Mid Glamorgan is in Wales, so the planning and building rules set out below are the ones that apply. We confirm the details with the council before we quote.
In Wales, rendering or cladding may need planning permission in conservation areas, and listed buildings need consent.
Building Regulations in Wales can require insulation upgrades when a large part of an external wall is renovated.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
How does the job run?
Free site survey
We begin by looking at the job in person. During the free survey we discuss options, materials and budget for external rendering, and photograph or measure anything the quote needs to reflect.
Written quote
Next you receive a written quote with a fixed price for the agreed specification. It lists what is included, what is not, and how payments are staged, so you can compare it properly.
Dates and permissions
Next comes planning the work itself. We set a start date that suits you, line up the right trades, and make sure any approvals for external rendering are in place before the first day on site.
Build and hand over
Our trades complete external rendering while your point of contact keeps you updated. When everything is finished, we clear the site, take away waste and go through the result with you before handover.
What you can expect from us
Questions about external rendering in Mid Glamorgan
How long does rendering take?
Rendering a typical semi-detached house takes around one to three weeks. Scaffolding goes up first, then removal of old render, repairs, beads and mesh. Base coats need time to cure before the finish coat. Weather has a big effect, because render should not be applied in rain, frost or strong heat. We give you an expected programme with the quote.
What time of year should rendering be done?
Render needs mild, dry conditions to cure properly, so spring to early autumn is ideal. Most render systems should not be applied when frost is likely, in heavy rain or in strong direct sun, which can dry it too quickly and cause cracking. We plan the programme around the forecast and may pause work if the weather turns, which protects the finish.
How much does it cost to render a house?
Rendering a typical 3-bed semi costs £6,400–£14,500, including scaffolding and preparation. As a guide, allow around £60–£120 per square metre of wall plus fixed costs for scaffolding and set-up. Sand and cement is the lowest-cost system, while silicone thin-coat costs more but needs no painting. Removing old render or pebbledash first adds noticeably to the price. We confirm a fixed figure after the survey.
